Anti-noise
Our expertly designed manhole covers feature meticulously machined contact surfaces that align perfectly with the manhole frame. This precision ensures a seamless fit and effectively eliminates any intrusive noise, providing a tranquil urban environment.

Anti-slip
Ingeniously crafted with diamond-shaped block patterns on the manhole frame's surface, our design further includes an interconnected ring structure enhanced by strategically placed T-shaped protrusions. These features significantly elevate the friction coefficient between the asphalt base and the ring opening once laid on auxiliary roads, delivering superior anti-slip performance.

Anti-displacement
Securely anchored with durable bolts, as indicated by the small round holes in our detailed imagery, the manhole frame is designed to withstand construction pressures. This ensures that the manhole cover remains perfectly aligned during the use of road rollers, facilitating flawless and efficient road construction.

Anti-falling
Introducing the revolutionary five-prevention manhole cover, which includes an integrated anti-falling grid. This innovative feature is engineered to prevent accidental falls or injuries in the event that a manhole cover is displaced, ensuring utmost public safety.

Anti-theft
Our manhole covers incorporate a sophisticated anti-theft hidden box and a smartly designed opening folding plate beneath both the cover and the frame. This innovative solution replaces traditional anti-theft chains, effectively preventing theft and addressing rust issues caused by cavitation and water erosion, thereby prolonging the lifespan of the product.

FAQ

1. Casting process optimization category
Q: How to solve the problem of cracking in thin-walled die-casting products?
A: Suggest controlling the proportion of recycled materials to ≤ 30%, calculating the mold retention time based on a wall thickness of 1mm/3s, controlling the ejection delay within 0.5-2 seconds, and optimizing the mold cooling system.

2. Equipment and operation category
Q: How to handle emergency situations when the injection head is stuck in the goose neck area?
A: After the equipment cools down, try rotating the hammer head. If it cannot be rotated, replace the driver cylinder; Long term solution: It is recommended to upgrade the material of the material pot and regularly clean impurities.

3. Q: Is there intermittent discharge during material feeding?
A: Check if the nozzle is blocked (the gray section indicates blockage), which can increase the nozzle temperature by 5-10 ºC, shorten the nozzle departure time by 0.1-0.2 seconds, and moderately reduce the flow rate of the fixed mold cooling water.

4. Materials and Surface Treatment
Q: Does the casting have pattern defects after anodizing?
A: Adjust the uniformity of injection oil spraying and optimize the high-speed injection switching position; Regularly check the copper ion concentration in the oxidation tank (recommended ≤ 20ppm)
5. Mold maintenance category
Q: What should I do if the mold frequently sticks to the material?
A: Comprehensive solution: Reduce pouring temperature by 20-30 ºC Use polymer release agent Polish the surface of the mold cavity (use with caution for nitriding molds) Optimize sprue design to reduce metal liquid flushing
